Dooner,Buy the factory intake as it is a dual plane and will make more torque under 3500rpm for a non-stroked Poly 318 with high rear end gears (2.76-3.23). The Weiand will work well for Stroker application and with lower rear gears on a non-stroker Poly. Either way, buy the cast iron Poly intake and use it or you can easily resell it to finance your Poly build - whichever way you go.
The cast iron Poly intake made 440ft. lbs. of torque @ 3500rpm and 361HP @ 5000rpm for a special "Poly Street Stroker" engine I built recently; '66 Charger with high 2.76 gears that wasn't interested in power over 5000rpm; although the engine would certainly perform above 5000rpm I designed it to make all its HP & Torque to move the heavy Charger and be a killer street engine with docile manners.

I've got a chance to get a cast iron factory 4bbl intake for my Poly at $120 + $30 shipping. I already have a Wieand 7503 4bbl aluminum intake. I am planning to rebuild the Poly as a nice drivable street engine, hoping for about 325 to 375 hp (maybe stroked). I will also run a 727 automatic and the 2.76 rear gears. That will not change unless I figure out what overdrive trans will work best with the push buttons (I know it has to be modified to work together). Then I would change the rear gears. I just need to know which intake would work best for me. I don't want to go through the trouble of getting the intake, if the one I have will be just as good.
